CX-035499: Sacheen Alternate Station Service – Transformer Move Project (Update to Previous CX issued November 1, 2021)

Bonneville Power Administration (BPA) proposes to allow the Pend Oreille Public Utility District (POPUD) to upgrade the existing secondary station service transformer at Sacheen Substation. To upgrade the transformer POPUD would install a new 480/277 Y-Y pad mount transformer, a new CT cabinet, a new service disconnect outside of the substation fence, new underground trenching, approximately 350 ft of conduit and new medium voltage cables on the north side of the substation.
